Another Study Highlights Alopecia Areata Risk Following COVID19

COVID 19 Increases the Risk of Alopecia Areata

A study examining claims data from Japan and Korea showed that patients with COVID-19 infection were at increased risk for developing alopecia areata. Specifically, SARS-CoV-2 infection was associated with a 66 % increased risk of incident AA (aHR, 1.66; 95% CI, 1.38-1.99).

Interestingly, having severe COVID-19 infection increased the risk of alopecia areata, but having two or more doses of the COVID-19 vaccine before infection decreased the risk of developing AA.
